# Theory of Space： Visual Scene Dataset
This dataset provides pre-rendered 3D multi-room environments for evaluating spatial reasoning in Vision Language Models (VLMs). It is designed to support the **Theory of Space (ToS)** benchmark, which tests whether foundation models can actively construct spatial beliefs through exploration.
**Paper**: [Theory of Space: Can Foundation Models Construct Spatial Beliefs through Active Exploration?](https://huggingface.co/papers/2602.07055)
**Project Page**: [https://theory-of-space.github.io](https://theory-of-space.github.io)
**GitHub Repository**: [https://github.com/mll-lab-nu/Theory-of-Space](https://github.com/mll-lab-nu/Theory-of-Space)
## Dataset Overview
| Property | Value |
|----------|-------|
| Rooms | 3 |
| Total Runs | 100 |
| Objects per Room | 4 |
| Includes False-Belief Data | Yes |
## Usage
### Download
Download via Hugging Face CLI:
```bash
# Add huggingface token (optional, avoid 429 rate limit)
# export HF_TOKEN=
hf download MLL-Lab/tos-data --repo-type dataset --local-dir room_data
```
Or use the ToS setup script which downloads automatically:
```bash
git clone --single-branch --branch release https://github.com/mll-lab-nu/Theory-of-Space.git
cd Theory-of-Space
source setup.sh
```
### Sample Usage
To run a full pipeline evaluation (explore + eval + cogmap) using the provided scripts:
```bash
python scripts/SpatialGym/spatial_run.py \
--phase all \
--model-name gpt-5.2 \
--num 25 \
--data-dir room_data/3-room/ \
--output-root result/ \
--render-mode vision,text \
--exp-type active,passive \
--inference-mode batch
```
